No, the way you took them was fine. My strongest trip ever was on HBWR, but I took considerably more than you. That said, you are right to start low as HBWR is highly variable in effects from person to person.
I took HBWR 3-4 times a week for about six weeks and what I found was that the freshness and viability of the seeds made a world of difference. So, go through your seeds and crack the shell off and make sure the embryo is nice and plump. Then when you have enough put them, shells and all, in a coffee grinder and make dust out of them then stick them in 000 capsules take them like that.
I have an extremely strong stomach when it comes to seeds, HBWR and Morning Glory, but enough seeds to trip hard is going to probably upset your stomach. Weed is very good for that so try and smoke just enough to quell the nausea until you see how much effect the seeds have.
I tripped for about 12 hours with a 3 or 4 hour peak. However; I didn,t feel anything for about 3 hours and re-dosed early and it blew my mind. As I said it was the strongest trip of my life and I have tripped dozens of times.
So be safe and have fun.
BTW, if you do a large dose you might want a trip sitter, I needed one, but didn't know it until I needed one.
